Abstract: ABSTRACT OF THE DISCLOSURE An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formu-lations when incorporated as a plasticizer therein. Certain paraffins or alpha-olefins and blends thereof when chlorinated to selected final chlorine contents are compatible with poly-sulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. The improved plasticizers are not sub-ject to significant heat loss. Modified polysulfide rubber sealant formulations are disclosed which incorporate as a plasticizer the improved chlorinated hydrocarbon, and which are useful as glass or window sealants, particularly as glass or window sealants between the panes of a thermal pane or multi-pane insulating window structure. The improved plasticizers are non-fogging in polysulfide rubber formulations and are not sub-ject to significant heat loss.

Abstract: ABSTRACT OF THE DISCLOSURE A touch keyboard system for in a control system for a microwave oven comprises - a touch plate sectioned off into a plurality of areas, each area representing certain information to be entered into the control.          The system includes a programmable digital logic control circuit which enables a user to program information into the digital logic control circuit. The digital logic control circuit allows a user to program information into the control, relating to the amount of time the magnetron tube is to be energized.  The control also allows the user to select the power level or duty factor at which the magnetron is energized from three different levels, thus providing a choice to the user as to whether the magnetron is to be operated in a defrost mode, a slow cook mode or a cook mode.  The control allows the oven to be operated in a single stage manner whereby the micro-wave oven is operated in the defrost, slow cook or cook modes for the amount of time programmed into the control by the user.  Alternatively, the oven may be programmed in a two stage manner whereby the user determines the duration of the defrost portion and the duration of the cook portion in a combination defrost-hold-cook mode.  The user may also program the oven so that it operates in a combination defrost-hold-slow cook mode.  The user programs information into the control by means of the touch plate and in-formation in the control such as the time of day, the time remaining in any of the microwave modes, the time remaining in the timer mode, or the in-formation which has been entered by the user is displayed to provide a visual feedback to the user.

Abstract: TITLE:              CONDUIT SEALING SYSTEM     ABSTRACT OF THE INVENTION     A seal system is provided with a series of annular seal assemblies separated by relatively rigid spacing members and may be preferably adapted to selectively sealing engage a packer apparatus within a well bore conduit, during the completion or work over of a subterranean oil or gas well.  Preferably, each seal assembly comprises four annular seal members in sequence.  The outermost seal members are formed from a thermoplastic polymer having a co-efficient of expansion greater than that of the rigid spacing members and the conduit, with physical resistance to corrosive chemicals and high temperature and pressure environments.  The outermost member has a physical hardness sufficient to withstand extrusion into a gap defined between the rigid spacing member and the conduit by pressure transmitted from the rigid spacing member.  One of the inner seal members is a flexible perfluoro polymer with enhanced permanent set and cold flow.  The second of the inner seal members is an elastomer derived from the co-polymerization of tetrafluoroethylene and perfluoroethers.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for measuring the amount of previously applied torque to a fastener.  A transducer is utilized to sense the amount of a subsequently applied torque to the fastener and provides an output signal representative of the applied torque.  The torque is applied until further motion or breakaway of the fastener is obtained.  Typically, the signal from the transducer increases until breakaway of the fastener is obtained and then the signal decreases momentarily to a valley before it again increases with further applied torque.  A positive peak detector senses the maximum positive output of the transducer before the signal begins to decrease.  A negative peak  detector senses the minimum negative output of the transducer before the signal again increases.  The negative peak detector is energized by a switching network upon detection of a negatively sloped signal from the transducer.  A display coupled to the output of the negative peak detector provides a visual indication of the valley torque which is closely associated with the amount of torque originally applied to the fastener.

Abstract: ABSTRACT         The disclosure is directed to an improved liner assembly for an ore grinding mill.  The liner assembly is of the segmented type, comprising a first plurality of segments which are mounted directly to the shell of the mill, and a second plurality of segments each of which is secured to an associated first segment independently of the shell.  The first segments are formed from material which is resistant to impact, and the second segments are made from material which is highly resistant to abrasion.  As constructed, the second segments can be replaced after a period of wear from inside the mill, avoiding the necessity of replacing the first liner segments which required working teams both inside and outside the mill. In one embodiment, the second segments are L-shaped and are secured to the first segments by nut and bolt assemblies that are generally aligned with the shell surface to resist shear forces.  In a second embodiment, the first and second segments resist shear forces with a tongue and groove configuration coupled with nut and bolt assemblies that are transverse to the shell surface.  In a third embodiment, the first segments define a longitudinal, axially extending channel that opens toward the center of the shell.  The channel has opposed inner surfaces that converge toward the center of the shell.  The first segments are secured to the shell by bolt and nut assemblies that extend through the segment from the bottom of the channel and through the shell.  The second segments are constructed to slide into the channel, having converging sides that are retained by the converging channel sides. The second segments thus protectively overlie the nut and bolt assemblies that secure the first segments to the shell.

Abstract: ABSTRACT   A radio paging system is described in which a transmitter transmits a calling signal and display information signals to remote receivers.  In the novel system, immediately before each word transmitted, a word discriminating signal is transmitted which indicates whether the word to be transmitted is a calling signal word or a display information word.  The receiver recognizes the word discriminating signal and, as appropriate, either decodes and detects a calling signal to provide a detection signal or decodes a display information signal to provide a decoded signal which is then displayed.  The invention makes better use of the available communication channels than prior systems.
